I am often a victim of the 3 p.m. slump. My brain goes fuzzy. My eyes feel tired. All I want to do is nap. Lately, I have been taking myself out for a walk at 2:30 to prevent the afternoon "drowsies." Melatonin, a hormone signal that tells the brain it is time to sleep, is not produced in bright light. So going for a 20 minute walk in the bright afternoon light will combat that sleepy feeling. Bright light has been shown to increase alertness and boost brain activity — just what I need to make it get the rest of my work done. The trick is to head outside before you feel drained. The combination of brisk walking and bright light definitely combats my energy slump. Try it and see if it helps you make it through to the end of your workday.
